TWO-CYLINDER STRUCTURE FOR LOCOMOTIVES.

Application filed July 16 The object of our invention is to make alocomotive cylinder structure, having two high pressure cylinders, as asingle casting, and to so design the structure that the outer walls ofthe passages can be inspected from the outer side.

In the accompanying drawings:

Fig. 1 is a front elevation of a locomotive cylinder structureillustrating our invention Fig. 2 is a sectional plan view on the line22, Fig. 1;

Fig. 3 is a transverse sectional view on the line 3-3, Fig. 2;

Fig. 4 is a sectional view on the line 4-4, Fig. 3; and

Fig. 5 is a-sectional view on the line 5-5, Fig. 3.

11 are the side frames of a locomotive upon which the cylinder structure2 is mounted. The cylinder structure 2 is made as a single casting,having flanges 3 which are bolted to the frames 11.

The cylinder structure extends beyond the frames at each side, and inthe extensions are the cylinders L-A and cylindrical valve chests 55.

The saddle 6 is located at the centre of the structure and is curved toconform to the boiler to which it is attached.

The steam inlet ports 7-7 communicate with the valve chests 5-5, asshown, and with steam supply pipes leading from the boiler.

Passages 88 connect the cylinders 4l4 with their valve chests 5-5, asshown in Fig. 4. In each valve chest are two bushings 9 9, and thecylinders are preferably bushed as shown.

In the present instance the steam chambers of the valve chests are atthe centre and the exhaust passages are at the ends of the valve chests(see Fig. 4)

In all the and valve chests have been omitted.

figures the heads for the cylinders I 1927. Serial N0. 206,180.

The exhaust passages 10-40, which lead from the passages at the ends ofthe valve chests, are gradually tapered from the valve chests and curvedupwards at each side of a central partition 11, terntiinating at theexhaust nozzle 12.

The outer walls of the exhaust passages are exposed and can be examinedthrough openings 13 in the end walls 14 of the cylinder structure, sothat if leaks are discovered the openings can be readily closed bywelding.

In a central web 16 are additional inspection openings 15, that accesscan be had to the portion. of the casting between the cylinders and theparts of the exhaust passages exposed through the openings 13.

By the above construction, all the walls of the structure within thecylinder structure are exposed for examination and for repairs ifnecessary, and as all of the outer surfaces of the walls are exposed,every part of the structure can be readily examined, and any defectsdetected can be readily remedied.

The structure is preferably a unitary steel casting, although it will beunderstood that in some instances it may be of cast iron or other metalswithout departing from the main feature of the invention.

We claim:

An integral cylinder saddle having a cen tral web, cylinders and valvechests formed in the saddle, and having exhaust passages leading fromthe cylinders to an exhaust nozzle, said exhaust passages being in theform of a tubular casting; and a supporting frame enclosing said tubularcasting, Laid frame having openings through which access may be had toall parts of the outside walls of said tubular casting and havingopenings in the central web thereof.
